KENNETH L. EDDY, OF CHICAGO, ILLINOIS, ASSIGNOR, BY MESNE ASSIGNMENTS, 'IO AUTOMATIC UTILITIES CO., A CORPORATION OF ILLINOIS.

LOOSE-LEAF DEVICE.

Specification of Letters Patent.

Patented J an. 9, 19117.

Application filed March 20, 1914.. Serial No. 825,947.

To all whom it may concern Be it known that I, KENNETH L. EDDY, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Loose-Leaf Devices, of which the following is a specification.

My invention relates to that class of devices which are designed to lift a card or group of cards above their normal plane, by the use of a device comprising a. longitudinally movable bar, which is suitably connected by means of toggles to a rising bar, which is designed to engage pins depending from the lower edge of the cards in the box or casing.

In devices of this character, ithas been found difiicult to obtain the necessary lift or elevation of the cards within the space provided in the ordinary card index device. This has resulted in the lowering of the angle between the two pivoted points of the toggles to such an extent that it is very difficult to move the longitudinally movable bar by the pressure of ones thumb at the first part of the movement. As soon as it is moved slightly, so as to vary the angle, it then raises easily.

My invention has for its object to provide means which will overcome this difficulty and which will permit of the rising bar lying fiat against the longitudinally movable bar and yet will insure its raising easily during all portlons of its movement.

My means of accomplishing the foregoing objects may be more readily understood by having reference to the accompanying drawings, which are hereunto annexed and are a part of this specification, in which:

Figure 1, is a fragmentary sectional view of a card index casing, provided with a device of this character equipped with my improvements. Fig. 2, is an enlarged fragmentary detail view showing a modified form of applying my invention. Fig. 3, is a top or plan view of a card index device.

Similar reference numerals refer to similar parts throughout the entire description. As shown in the drawings, 1 is a casing which is provided with forward and rear end walls 2 and 3 respectively. I A longitudinal bar 4, the forward end 5 of which extends upwardly and is projected outwardly through the wall 2 is provided with a push button 6 of suitable size and shape. The rising bar 7, which is secured to the longitudinally movable bar 4, by means of toggles 8 and 9, serves to raise the cards.

A roller 10, is carried by the end of the rising bar 7, and is designed to minimize tween the pivots 14 and 15 of the toggles 8 and 9, with a result that the rising bar 7 starts on its upward movement with the utmost freedom and without the slightest difiiculty, even when the bars 4 and 7 lie flat against each other, as shown in Fig. 2.

Although I have shown the device in connection with the structure shown in my copending application, bearing Serial No. 825,948, filed March 20, 1914, it is obvious that I do not desire to be limited to the said combination, but that my invention may be employed in any device of this character.

Having described my invention What I regard as new and desire to obtain by Letters Patent is: l

1. In a card index, a case, cards arranged in groups, a rising bar to lift the cards of the respective groups, a roller mounted in the inner end of said rising bar, a guide plate for said roller having its lower edge bent inwardly for the purpose set forth substantially as described.

2. In a device of the character described the combination with a casing having a plurality of cards therein, a rising rod for displacing one or more cards from their normal position, a roller mounted in the inner end of the rising rod, with a guide for said roller consisting of a metal plate the lower end of which is bent inwardly for the purpose set forth substantially as described.

3. In a device of the character described the combination with a casing having a plurality of cards therein, a rising rod for displacing one or more cards from their normal position, a roller mounted in the inner end of the rising rod, with a guide for said roller consisting of a metal plate, the lower edge of said plate being curvedinwardly, for the purpose set forth substantially as described.

I In witness whereof, I have signed the foregoing specification.
